Do fish float when they die?
Most fish are slightly denser than water, so sink immediately after death. However, like a drowned human, they become more buoyant over time as bacterial decomposition produces gases inside the body. Usually, enough gas builds up in body cavities to make the corpse float, like an inflated balloon.
Is my fish dead or resting?
Moving your fish using a fish net is the best way to detect if your fish is dead or sleeping. If your fish suddenly try to get free from the net, they are sleeping; if they don’t show any movement, they are dead. Also, look for the movement of gills to detect whether they are resting.
